Publication number: 20230417855Abstract: Aspects presented herein may improve the performance and accuracy of RF-based positioning. Aspects presented herein may enable a device to use RF Doppler measurements to detect and mitigate multipath effects in RF-based positioning. The RF-based positioning may include satellite navigation, terrestrial positioning system, and/or indoor positioning. In one aspect, a UE receives, via a receiver, signals from one or more entities. The UE determines whether each received signal is a multipath signal based on a Doppler shift measurement. The UE de-weights or excludes one or more signals of the received signals in estimating a position of the UE based on whether the respective received signal is determined to be a multipath signal.Type: ApplicationFiled: June 28, 2022Publication date: December 28, 2023Inventors: Yuxiang PENG, Ning LUO, Bo ZHENG, Jingchao BAO, Min WANG, Gengsheng ZHANG, Yinghua YANG

Publication number: 20230204796Abstract: Global Navigation Satellite System (GNSS) receivers can provide more accurate positioning when augmented using Real-Time Kinematic (RTK) or Differential GNSS (DGNSS) corrections. Techniques described herein leverage multi-constellation, multi-frequency (MCMF) measurements taken at a base station at first and second times to generate correction information that can be used to detect and correct a bias (or offset) in the location of the base station. This bias may be detected by a rover station, or by the base station itself.Type: ApplicationFiled: August 20, 2020Publication date: June 29, 2023Inventors: Min WANG, Ning LUO, Yinghua YANG, Ling HAN

Patent number: 11668840Abstract: A Real-Time Kinematic (RTK) solution is provided to mobile devices having multi-constellation, multi-frequency (MCMF) functionality, in which a single base station may have a baseline much farther than traditional base station. To enable this, embodiments account for differences in atmospheric effects between the rover station and base station when determining a GNSS position fix for a mobile device (rover station), allowing for a separate tropospheric delay error for a base station to be determined. Embodiments may use additional satellite measurements for which no RTK correction is available, and may further use orbital clock correction for these additional satellite measurements.Type: GrantFiled: August 20, 2020Date of Patent: June 6, 2023Assignee: QUALCOMM IncorporatedInventors: Min Wang, Mangesh Chansarkar, Ning Luo, Gengsheng Zhang, David Tuck, Bo Zheng, Yinghua Yang, Han Zhang

Patent number: 11619745Abstract: Techniques for enhanced Global Navigation Satellite Systems (GNSS) position determination can include capturing an image, from a camera, of obstructions near a mobile device. Orientation information regarding the camera can is used to determine where, in the image, the horizon is situated, and which portions of the sky are blocked by the obstructions from the perspective of the mobile device. Information regarding the location of satellites in the sky is obtained, based on an estimated position of the mobile device. Obstructed satellites can then be identified by comparing the location of the satellites with the obstructed portions of the sky. In a GNSS position determination, information received from the obstructed satellites can then be disregarded or de-weighted accordingly. In some embodiments, the information regarding the blocked portions of the sky can be sent to a server and/or shared with other nearby mobile devices.Type: GrantFiled: October 29, 2019Date of Patent: April 4, 2023Assignee: QUALCOMM IncorporatedInventors: Ning Luo, Gengsheng Zhang, Bo Zheng, Yinghua Yang, Arnold Jason Gum
